The upper arm type electronic blood pressure meter comprises: a housing including a bottom case 11, a front case 12, an upper cover 13, and a rear cover 14, the front case 12 being connected to a top of a front side portion of the bottom case 11, the front case 12 being formed with a mounting port penetrating front and rear; the upper cover 13 is detachably arranged on the top of the rear part of the bottom shell 11, the rear cover 14 is arranged on the back of the front shell 12 in a covering manner, and the rear cover 14 is provided with a clearance opening corresponding to the mounting opening; a sleeve 20, wherein the sleeve 20 is installed at the installation opening, and an air bag component is arranged in the sleeve 20; the air pump 30 is arranged on the bottom shell 11, and the air pump 30 is communicated with the air bag assembly through an air path assembly; the air valve 40 is arranged on the bottom shell 11 and is communicated with the air path assembly; a pressure sensor 50, wherein the pressure sensor 50 is mounted on the bottom shell 11 and is communicated with the air path assembly, and the pressure sensor 50 is used for detecting air pressure in the air path assembly; the first circuit board 60, the first circuit board 60 is detachably mounted on the rear portion of the bottom shell 11, and the first circuit board 60 is electrically connected with the air pump 30, the air valve 40 and the pressure sensor 50.

In this embodiment, the housing is irregularly shaped as a whole; the bottom shell 11 is used for supporting the whole medical full-automatic upper arm type electronic sphygmomanometer, the front side part of the bottom shell 11 is a part which is close to a user in a use scene, and the rear side part of the bottom shell 11 is a part which is far away from the user in the use scene. In the use scenario of the medical full-automatic upper arm type electronic sphygmomanometer, the arm of the user passes through the sleeve 20 from front to back, and the upper arm is stopped in the sleeve 20, so that the air bag on the sleeve 20 can be wound on the upper arm of the user.

The air pump 30 is used to inflate the air circuit assembly, and air flow can flow to the air bag through the air circuit assembly, and the inflated air bag can generate air pressure to the arm blood vessel of the user. The air circuit assembly may be provided as a multi-way tube or as a hollow member having a plurality of air vents, without limitation.

It will be appreciated that the air pressure in the air path assembly is the same as the air pressure in the air bag, and if the air pressure in the air bag changes, the air pressure in the air path assembly also changes, and the change in air pressure in the air path assembly is detected by the pressure sensor 50, so that the blood pressure of the user can be reflected.

The principle of detecting blood pressure by the pressure sensor 50 and the air bag can refer to an oscillometric method or an oscillation method, the principle is that the inflation amount of the air bag wound on the upper arm is automatically adjusted, the pressure is changed, blood flow has certain oscillation waves through a blood vessel, the pressure sensor 50 receives the blood flow and is gradually deflated, the pressure and the fluctuation detected by the pressure sensor 50 are changed along with the change of the oscillation waves, the moment with the maximum fluctuation is selected as a reference point, and based on the reference point, the fluctuation point with a certain value is searched forwards as the systolic pressure, and the fluctuation point with a certain value is searched backwards as the diastolic pressure.

After the detection of the blood pressure of the user by the pressure sensor 50 is completed, the air valve 40 needs to deflate the detection air path, and timely removes the air pressure of the air bag on the blood vessel of the user, so as to prevent the damage to the user.

The upper cover 13 and the rear cover 14 are separately provided, the upper cover 13 covers the top opening of the rear portion of the bottom case 11, and the rear cover 14 covers the back opening of the front case 12. When the first circuit board 60 needs to be overhauled, only the first circuit board 60 needs to be removed after the upper cover 13 is disassembled or the first circuit board 60 needs to be overhauled directly. Since the upper cover 13 is only provided to the rear portion of the bottom case 11 and is separated from the rear cover 14, the front case 12 and the rear cover 14 are not affected by the disassembly and assembly of the upper cover 13, thereby reducing the difficulty of maintenance of the first circuit board 60. The first circuit board 60 may be fixed in the bottom case 11 by a buckle, or may be fixed by a screw, which is not limited herein, and only needs to satisfy that the first circuit board 60 is detachable.
